今天继续完成测试用例的相关功能,因为我们这个平台内容比较多,一个测试用例可能关联的属性也比较多,具不完全统计大概有:环境、项目、服务、模块、接口、用例级别、创建人和编辑人等。所以这块功能在写的时候都需要关联很多表去查询或者写入数据。不做不知道,原来自己之前掌握的MySQL语句的知识,太浅薄了。

今天主要用到了MySQL语法case when then else endFIND_IN_SET函数和多种非必选条件和判断语句的练习(这个其实就是复杂一些)。中间还发现了mybatis其实替用户做了一些兼容性的处理,比如我在拼WHERE条件语句的时候,每个都是and condition,本来还担心要不要去掉第一个and,经过咨询前辈才知道,这块不要直接拼WHERE语句,可以用​​<where></where>​​​这个**​​mybatis​​**语法即可完成,非常友好。今天学到的第二个就是异步查询转同步,在之前的文章已经讲过了,今天算是又实践了一下,写实际的业务跟练习区别还是挺大。

MySQL语法case when then else end实践

需求大概就是从很多非必传参数里面搜索库里面的用例,这些条件包括:环境、项目、服务、模块、接口等等,如下图

我的开发日记(六)_搜索

然后接口传参都是​​int​​​和​​string​​​类型,​​0​​表示全部,各个选项状态不一。在处理搜索框的搜索类型时候,我提前做了判断,如果内容是个数字,那么我就认为是搜索ID,否则我认为是搜索用例名(模糊匹配),因此我引入了另外一个type作为记录。接收参数的类代码如下:

class CaseSearchBean extends AbstractBean {

private static final long serialVersionUID = -869483426556;

int id

@Min(value = 1L)
int uid

int envId

int apiId

@Range(min = 0L, max = 2L, message = "是否本人参数错误")
int isMyself

@Range(min = 0L, max = 2L, message = "是否可用参数错误")
int isUsed

int serviceId

int moduleId

@Min(value = 1L)
int pageNum

@Range(min = 5L, max = 10L)
int pageSize

int projectId

String testQuery

/**
* 处理搜索类型,1:用例名模糊搜索,2:用例id精确搜索
*/
int type


def init() {
if (StringUtils.isEmpty(testQuery)) return
if (SourceCode.isNumber(testQuery)) type = 2
else type = 1
}


}

由于业务不多,中间的​​service​​​和​​mapper接口​​就不放了。

异步查询转同步

相关文章和测试方案请参考:

  • 服务端性能优化之异步查询转同步
  • 异步查询转同步加redis业务实现的BUG分享

这个地方主要是因为用例关联的项目和版本比较多,返回格式要求是​​array<object>​​​格式的​​id+name​​形式对象,所以单独拿出来查了。业务实现类的相关代码如下:

@Override
public TestCaseAttributeBean getAttributeById(int id) {
TestCaseAttributeBean bean = new TestCaseAttributeBean();
bean.setId(id);
CountDownLatch countDownLatch = new CountDownLatch(2);
getAttributeById(bean, countDownLatch);
getCaseProjectRelation(bean, countDownLatch);
try {
countDownLatch.await(10, TimeUnit.SECONDS);
} catch (InterruptedException e) {
CaseException.fail("查询用例信息发生错误:" + e.getMessage());
}
return bean;
}

@Async
@Override
public void getAttributeById(TestCaseAttributeBean bean, CountDownLatch countDownLatch) {
try {
TestCaseAttributeBean attributeById = testCaseMapper.getAttributeById(bean.getId());
bean.copyFrom(attributeById);
} finally {
countDownLatch.countDown();
}
}

@Async
@Override
public void getCaseProjectRelation(TestCaseAttributeBean bean, CountDownLatch countDownLatch) {
try {
bean.setVersionList(testCaseMapper.getCaseProjectRelation(bean.getId()));
} finally {
countDownLatch.countDown();
}
}

bean代码

本来打算用AbstractBean类的​​copyFrom()​​方法的,发现不太好,只能重写了一个。

class TestCaseAttributeBean extends AbstractBean {

private static final long serialVersionUID = -1595563071153477L;

int id

int apiId

String apiName

int envId

String envName


int moduleId

String moduleName
String name

int serviceId

String serviceName

List<ProjectBean> versionList

/**
* 用于异常查询结果赋值
* @param bean
*/
@Override
def copyFrom(TestCaseAttributeBean bean) {
this.id = bean.getId()
this.apiName = bean.getApiName()
this.envId = bean.getEnvId()
this.envName = bean.getEnvName()
this.moduleId = bean.getModuleId()
this.moduleName = bean.getModuleName()
this.name = bean.getName()
this.serviceId = bean.getServiceId()
this.serviceName = bean.getServiceName()
}

}

当然还需要在启动类的增加注解,开启异步任务功能。

@EnableScheduling
@MapperScan(value = "com.okay.family.mapper")
@ServletComponentScan
@EnableAsync
@EnableTransactionManagement
@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
public class FamilyApplication {

public static void main(String[] args) {
SpringApplication.run(FamilyApplication.class, args);
}


}
